Wow, sosick that is horrible! Thanks for informing us about this, I had NO idea it could be possible to get so serious. I agree, go for the hydrogen peroxide, heard of that being used often for such problems.

How sad that a dentist might not be much help, when they did this in the first place. Should be their job to fix it, but as always it seems to be the patient who suffers and has to rectify it all.
